Fountainhead Regional Park has one of the best trail systems in the northern Virginia area. The green loop is enjoyable, with berms, tabletops, bridges, as well as more natural features like exposed rocks and roots. It's a stand alone beginner loop and also serves as the feeder for both Blue and Black loops. Stay right, and over, at the bridge to return to the lot and stay on Green.
